GUIDEMEC'HANISM." n'

Appnoauonmed August 27, 192,3., 'serial No. 659,494.

To all 107mm t may concern:

Be it known that I, SAMUEL ELDER, a citizen of the United States, residing at Vashington, in the District of Columbia,

' have invented certain new and useful Tm*- proveinents in Guide Mechanism, of which the following is a specication.

This invention relates to a new and improved guide mechanism and more particularly to mechanism adapted to guide the travel of the boards or plate carrying members in engraving presses or similar `apparatus. f f

In certain types sof'presses particularly adapted for use in producing engraved notes, bonds, and the like, the engraved ment of the boards and also a tendency` to enter the straight guides with afheavy shock or blow. l y

It is an object of the present invention to provide guide means upon the table and vas-k sociated boards adapted to guide and control the boards at the points in their travel where theyr change direction.

It is a further object to` provide a construction of this character whichy is simple in design and which may be applied to existing structures without material alteration therein. f n

Other and further objects will appear as the description proceed i In the embodiment shown herein yfor pur poses of illustration, the guide means takesu the form of spring pressedplfunge'rs kcarried with'the plate carrying boards. and asso'- ciated parts, the upper pressA mechanism' be-` Vof Figure 2;/and

accompanying fd'ravl p l l, of 'eachstraight run, a depressing guide 27 Figure 1 is a plan View of a 'press'table' Figure I3 is an elevation 'of the board; y Figure 4 isa section taken on line 4 4 Figure 5'is an enlarged sectional detail taken on line 55 of Figure 1, showing the guide plunger construction. n

Referring now to igure 1, the table 6 is provided with the draft chain 7 carried in the bed of the table. an approximately Irectangular path passing about the driving sprockets v8 and the idler sprockets 9. vThe sprockets 8 are driven by means of the gear wheels'l() carried upon the same shafts which gear wheelsmesh with the main gear 11.

Thechain 7 is provided with the' spaced draft pins 12, each of which entersa bear- This chain travels in ing 13 in the lower'side of a plate-carrying board 14. AThis connection permits ythe direction are out of engagement Vwith' either of these guides and arey also out of engagement with the curved'connection portions 17 and`18 of the guide surfaces. The present inventionL provides'means for guiding the boardsy during thisportion of its travel.

` lThe normal direction of movement of the boards is counterclockwise as seen in Figure l; plungers 19, oneof'which is shown in detail in Figure 5. This plunger 19 is fitted into a bore 20 in the table member 21.y The re! 'duced lower portion `,22 of the .plunger'is surrounded by the spring 23 which tendsfto thrust the plunger upwardly. The plunger is retained in place by the threaded [collarl 24 against Awhich the flange 25 ofthe plunger bears. g gers are the guide channels 26 and depressing guidesl 2T' formed in the "plates Q8 seay n cured to thecorners ofthe inner face of the boards 14. l l i Inthe operation of the press, as theforward edge `of ya. board approaches the end engagesv the corresponding guide plungerr 19 and depresses ythat l"plunger so, thatfit bears against the under ksurface ofthe board `as the board continues to travel. As this travel `the boards whenmaking their change of The table'is `providedwith four guide f Co-operating with rthese plunis continued,vthe plunger head reaches the f entering portion 29 of the aligned guide channel 26 and the plunger spring presses it upwardly into this recess. By aligned guide channel is meant the guide channel upon the opposite edge to the depressing guide, the depressing guide being upon the front edge and the guide channel adjacent the rear edge of the board. The engagement of this pin with the channel and the engagement of the draft pin with the board together define tWo points limiting and controlling the movement of the board and it is guided as it makes its change of direction. It is also caused to enter evenly Aand Without undue jar between the succeeding guide- Ways l5 and 16. Immediately after thefor- Ward end oi the board has entered these guideways, the rear end clears the plunger 19 Which remains in position to guide the succeeding board. It will be noted that the recesses 27 are curved upon an arc corresponding to that made by the sprocket chain 7 about the sprocket AWheels .8 and 9. This curveis necessary since the planks mo-ve upon that .curve during their change of direction.

As during the course of a single trip around the table, the four edges of the board areV in turn the front or leading edge, it is necessary to provide all.` four corners of the board with identical recesses 26 and 27.

` 'Ihe various boards are, of course, identical.

IVhile this guide mechanism has been described particularly in connection With its application to anengraving press, it may obviously be applied to other constructions involving the Acontinuous movement of boardsor similar members. It is my intention. to cover allr such modifications as come Within the scope of the appended claims.

`1. yA movable member, guide grooves formed in said member, supporting means n for saidmeinber, means. adapted to move said memberpthroughha closed path, ,and guide members carried bythe supporting means-.adapted to coact with the guide lbed ofthe press, guide members extending grooves` said movable *member to guide it .during change of direction of movement. 2. In a printing press, a movable plate carrying member, a press table having a bed therein, means for moving said plate carrylng member through a closed path upon the from` the press bed, and guide channels formed inl the plate carrying member adapted to coact with the guide members to guide the plate carrying member during change of direction of movement. y Y.
